[Rhodes22-list] anchoring

[Peter Thorn]

Bill,

In coastal NC when people use "dragging the anchor" it means the anchor has
broken loose (usually from a mud bottom) from a previously good set.  Most
often the pull direction changes as a result of changing wind or current.
Tropical storm Hannah, a non-event compared to Ike, brought 60 mph winds to
the creek and this caused two boats (out of 75-100) to drag their anchors
and wash into the marsh.   I think you are discussing lunch anchoring.

Regards,

PT

Ben,

In order to set the anchor you must put tension on it.  This pulls the 
rode taut.  When there is no wind or current, the rode will lie flat on 
the bottom, or float to the surface if it is a floating rode.  But it is 
not holding the boat in place.

What most people call "dragging the anchor" is usually "dragging the 
chain".  If you fail to set your anchor -- which you will fail to set 
properly if you never draw the rode taut -- you can drag the chain all 
over the place, without ever properly setting the anchor.  If you draw 
the rode taut and properly set the anchor it just won't drag. 

A very small anchor can be used to hold a very large boat in place if 
the anchor is properly set.  It is much easier to set an anchor with an 
all rope rode.  The chain portion of the rode does not change the angle 
of pull.
